Sahih al-Bukhari, Hadith 5180 ⓘ
Narrated Anas bin Malik: Once the Prophet saw some women and children coming from a wedding party. He got up energetically and happily and said, "By Allah! You (i.e., the Ansar) are the most beloved of all people to me."
حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ الْمُبَارَكِ، حَدَّثَنَا عَبْدُ الْوَارِثِ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ صُهَيْبٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ أَبْصَرَ النَّبِيُّ صلى الله عليه وسلم نِسَاءً وَصِبْيَانًا مُقْبِلِينَ مِنْ عُرْسٍ، فَقَامَ مُمْتَنًّا فَقَالَ " اللَّهُمَّ أَنْتُمْ مِنْ أَحَبِّ النَّاسِ إِلَىَّ " .
